GUIDE FOR THREAD-CUTTING TEMPLES.

Specification of Letters IPatent.

Patented June 1, 1915.

Application filed September 10, 1914. Serial No. 861,145.

of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to thread cutting temples for looms and has for its object to provide means to guide or direct the filling end into the field of action of the thread cutting device on the temple and also to hold the filling end in the field of action of the said device. Automatic looms employing thread cutting temples are also commonly provided with filling parting and holding devices which sever the filling of the filling carrier abandoned upon replenishment and then carry the parted end forwardly, bringing it into the field of action of the temple thread cutter so that it may be again severed close to the selvage. But the parted end is not infrequently jerked from or released by the device holding and carrying it forward so that as a result, the end is dropped, whipped or snapped out of the field of action of the temple thread cutter, so that severance adjacent the selvage is not offected.

The object of this invention is to present means for eliminating so far as possible this defect in operation and insuring the severing of the filling end adjacent the selvage.

The nature and object of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

The drawings show so much of an automatic filling replenishing loom as is necessary to an understanding of this invention.

In the drawings: Figure 1 is a top plan view of the right hand end of a portion of a Northrop automatic filling replenishing 1 H loom embodying a preferred form of the present invention, and Fig. 2 is a perspective view of a portion of the temple, temple thread cutter and guiding devices embodying this invention. v

No detailed description of the general mechanism of the loom is necessary to an understanding of this invention.

The temple and thread cutter are for convenience, herein illustrated as of generally similar construction to that shown and described in the patent to W. F. Draper and E. S. Stimpson, No. 585,465 granted June 29, 1887. The stand 1 of the loom temple is secured in the usual manner to the breast beam of the loom. In this stand is mounted the slide bar 2 of the temple which carries at its rear end, the pod 3 and cap 4 between which is journaled the usual toothed roller.

The thread cutting instrumentality is mounted and works in the rearward end of the strand 2 and comprises a cutting blade 5 and a coiiper'ating hook shaped double blade 6 which has a forwardly and rearwardly reciprocating and also an oscillatory movement, all as described in the said patent to Draper and Stimpson so that when the filling end extending from the fell is brought between the blade 5 and the double blade 6 it will be severed. 1

As already explained, the filling end of the abandoned filling carrier is usually severed adjacent the filling carrier and then carried forwardly by suitable devices upon the abandonment of the filling carrier. Any suitable form of such filling, severing, and holding mechanism may be employed for this purpose but an appropriate form illustrated herein is the same as that disclosed in A. E. Rhoades Patent No. 1,134,487, granted April 6, 1915. In the said Rhoades patent, upon the call for filling replenishment, a carrier 7 is automatically moved rearwardly toward the filling carrier or shuttle about to be boxed at the transfer end of the loom. This carrier is provided with a head 8 and on the head is an abraiding surface 9 which cotiperating with the small abraiding surface upon the shuttle severs therebetween by abrasion the trailing filling. The severed end is at once caught upon the peripheral surface of the thread catching and holding member 10 also mounted on the head 8. This peripheral surface is of a thread adherent nature being described as composed of felt, cloth or similar material. The carrier 7 then moves forwardly and carries with it the parted end of the filling 11 which extends back to the fell of the goods being woven. As the end is thus carried back it is brought into position so that it will be severed by the temple thread cutting blades 5 and 6. But the filling end may not be severed at the first operation of the cutting vblades 5 and 6; it may not be accurately V grooves-"or notches '12 are; sometimes pro vided topaid'in locating the. proper position of the filling end; for severance-byth'e; temr pl thread cutter; But these rareainsufiicienti to: guide oryhold the;filling-end;in position.
